《义务教育数学课程标准》指出:“学生学习应当是一个生动活泼的、主动的和富有个性的过程……”也就是说,新时期的小学数学课堂不应该再是简单的知识灌输,也不是死板硬套,而是要具有趣味性和开放性,以保护学生的学习兴趣,使学生在轻松的环境中找到学习的乐趣,成为课堂的主体。所以,在素质教育下,作为数学教师的我们要认真贯彻落实课改基本理念,要借助多样化的教学活动来构建具有趣味性和开放性的小学数学课堂,以为学生数学素养的全面提升做好保障工作。因此,本文就从以下几种教学活动 “Compulsory education mathematics curriculum standards,” pointed out: “student learning should be a lively, proactive and personalized process ...” In other words, the new era of primary school mathematics classroom should no longer be a simple knowledge instillation, Nor is it rigid and rigid, but to be interesting and open, in order to protect students’ interest in learning, to enable students to find the fun of learning in a relaxed environment, become the main body of the class. Therefore, under the education of quality, as a teacher of mathematics, we must conscientiously implement the basic idea of ​​curriculum reform, we should use diversified teaching activities to construct a fun and open primary mathematics classroom, in order to make students improve the overall quality of mathematics Guarantee work. Therefore, this article from the following kinds of teaching activities
